Pour the fat from the pan, set the pan over high heat, and add the wine. Boil, scraping up any browned bits from the bottom of the pan with a wooden spoon, until the wine is almost completely reduced. Add the stock and boil until it’s reduced by half, about 3 minutes. Return the turkey to the pan, stir in the remaining tablespoon butter, and cook for 1 minute to heat through.
Remove the turkey from the pan; pool the sauce onto a serving platter. Cut the turkey on the bias and set atop the sauce. Garnish with the fried sage and bacon.
